To all whom t may conce/rn. y

Be it known that we, GILBERT G. DAVIS and MATTHEW J. DAVIS, both residents of the city of Vancouver, in the Province of British Columbia, Canada, have invented certain new Aand useful Improvements in Log Rafts, of which the following is a speci# fcation. l

Our invent-ion relates to improvements in log rafts the objects of which are to provide [irst a means of construction by which a raft can he built up of a plurality of tiers of logs, the floor ofthe raft being fiat to permit of having great loading capacity with a minimum draught to facilitate the removal of the raft from shallow waters, another object is to provide for a minimum towing effort being required by arranging the several logs subject to immersion longitudinally of the raft, and a further objectis to rovide a means whereby the raft is securely bound together that it may be 'towed through rough seas without loss of logs. Our invention consists essentially of a raft floor of logs bound together upo-n which further tiers of logs are loaded and tbound, as will be more. particularly described in the following speciiication, in Which:-

Fig. 1 is a transverse section of our invention.

Fig. 2 is a sectional plan View taken on the line 2-2 of Fig. 3.

Fig, 3 is a longitudinal section and part elevation taken on the line 3 3, of Fig. 2.

In the drawings like characters of reference indicate corresponding parts in each figure.

The numeral l indicates a plurality of logs laid longitudinally of the raft to form a floor 2, the logs 1 being bound transversely together by ropes 3 which are fastened at their outer ends around a pair of side sticks t as at 5. The numeral 6 indicates a tier of logs of length equal to the width of the floor 2, the logs at opposite ends of the tier 6 being suitably bound down to the outer logs 1 of the floor 2 by cables 7. The numeral 8 indicates a further tier of logs laid transversely of the' floor, which are of similar lengt-h to those in tier 6. 9 indicates longitudinally disposed side logs running from end to end of the raft upon the outer ends of the logs forming tier 8, and l0 is a tier of logs laid transversely of the raft between the side logs.9.`

The numeral ll indicates a plurality of cables passing around one side stick 4 over the tier l0 and the side logs 9 and around n the opposite side stick 4, the opposite ends of the cable being bound; upon itself' as at 12. i

The numerals 13, and 15 indicate fur-y lther tiers of logs laid up upon the raft in the manner'before described,"16 being `furtherside logs disposed longitudinally'on both sides of the raft abutting the end`s`of the logs forming the tier l5, the end logs of the tier 13 being bound to the side logs Y 9 by cables 17.

When sufficient transverse tiers have vbeen laid, a tier 18 is superimposed with logs laid longitudinally to approximately cover the raft. 19 indicates a plurality of cables passing around oneof the side sticks 4 over the top tier 18 and around the other side, stick 4, the vcables being fastened back lupon.

themselves as indicated at 20. The numeral 21 indicates a plurality of cables which are first passed around any one of the llogs, forming the raft floor 2 and fastened upon themselves eachof which cables are brought up between successive tiers (as is more particularly shown in Fig. 3) and are brought out to the end of the raft overgany desired tier and are fastened securely to the outer end of the floor log fromv which they each started, thus preventing the ends of the raft from becoming dislodged during the towing of the raft in rough seas. The numeral 22 indicates a pair of cables attached adjacent one en d of the side sticks 4 and connected at their opposite ends to the tow iine (noty i l shown) of the tug. Y From the foregoing it will be seen thatA we have invented a raft which may vbe constructed for towing in shallow waters and which is bound in a manner to withstand rough seas without damage, and which can be readily and safely dismantled at destination.

What we claim as our invention is:

nl i

apart tiers, transversely ldisposed logs between said side logs and means for binding said side logs to the tier of transversely disposed logs next above the side logs, and means for binding the several tiers to the raft floor.

2. In a log rafts a raft floor comprising longitudinally disposed logs and binding means connecting the logs together, a plurality of tiers transversely disposed upon the floorside logs at the ends of certain of the spaced apart tiers and ineans for binding the endrnost transverse logs of a tier tothe side logs 'of tier next below. n f 3.11m a vlog raft, a 'raftrfloor coniprising longitudinally vdisposed logs and binding means connecting such logs transversely together, a plurality of tiers oi2 transversely disposed logs carried upon Lthe door, means for binding the endvniost logs of successive tiers ,oftra-nsverse logs to the raft floor adjacent its opposite ends'. v l i 4. In a, log raft, a raft floor comprising iiogev longitudinally disposed logs and binding means tor connecting such logs transversely together, a plurality of tiers oi' transversely disposed logs carried upon the iioor, a tier ot' longitudinally disposed logs upon the topniost transverse tier, side sticks bound at each side of the raft and to the raft floor, and means connected to one side stick and passing` over the topinost tier and secured to the other side stick to bind the several tiers together. l y Dated at Portland5 Oregbn, this 24th day of April, 1923. *l A GlLBERT G.
